Particles with less magnetization , large particle size (~250nm) but large remanence were dragged at higher rate by an external magnetic field than particles with large magnetization , small particle size (~20nm) but less remanance .
Can anybody explain this phenomena based on the above observations ??? , Apart from particle size and magnetization (Ms) , does remanance (Mr) play any important role in such behaviour ???
Please, could you explain with more detail the technique used to extract the particules.
Dear Carlos,
Assume that nanoparticles is suspended in water medium in a container , nanoparticles with less magnetization , large particle size (~250nm) but large remanence were dragged at higher rate by an external magnetic field [ placed at the bottonm of the container] than particles with large magnetization , small particle size (~20nm) but less remanance . magnetization and remanence were obtained from Hysterisis loop data
In such case , Is there any relation between Remanence (Mr) with an effect of external magnetic field on nanoparticles suspended in water medium with different particles size .
